T0 aZl whom it ma3/ concern:

Be il known that ,RALP]1 L.Lnonv, a citizen of the Unilod Stales, residing in ll1o counly, and State of Now York. have iuventod certain 1iew and usel'ul 1mprovoznm1is in Carburelcrs, of WlllCi'l the following is a specifica lion.

This invention is directed to the provision oi an improvod for1n ol carburetor adapted particularlv for use in couuoction with a gasolone engiue on an automobi e.

The object of the invention is 10 eiTeot certain improvonwnts in tl1o constr1miiou of (an lnueters. For this use, il1o improvemenls invol ring the prm'ision of a carburetor WlliCll is simple in coustrruclion and an lie manui'acturc:l al lovv (zou and witlr whieh a ,QO0l quality of gas, lreo from bul bles or minute drops of gasoleno, is obtaiued.

have illustraiod (ho neerred embodimeut of my iuvouion in the accompanying dr:uvings in xvlxiolu- Figure 1 is a central section of the carliurelr, Fig. 9 is a top view of the same, Fig. 3 is a section on .lino3-I5 of Fi 1, Fig. 4 is a view in elevation of a portion of (lie car l ureter and Fig. 5 is a sectional delail view on the line of Fig. 1.

Roforring to these drawings, tho carburetor consists of two circular receptaeles one witl1iu the ot-1r, a spiral passageway within 1lio space between these two receplacles, au opening from one reeopt aole to the othor al; ll1e botlo1n thereoi and valve nmolianism at the top of lie two receptaeles. The larger or ouler receptaolo is preferably a circular sheet-1nozal can I, sec-ured to and dependinq from a fra1uoplaie 2; the sxnaller receptaclo is a metallio tube 3 and is secured ai. its upper end to the plate 2 and at its lmver end to the botloni of fixe ran 1, tlns tube being concentric with can 1. lu the space between the eau 1 and tube 3 a spiral passagcwav of small pitch formed by a ribboxrof shootmetal 4, wound spirally on edgoi1pon.the

tube 3. Near ils upper edge the eau 1 lras au opening in lhe vall thereof t0 admit air to the top of tl1e spirally arranged passagewav and at the bottom of the tube 3 au opening is provided in the wall of (lie tube to connect the bottom of the spiral passageway with the inlrior of tube 3. The gasolene is admitted to the spiral passageway at the top thereoi' irom a pipe 5 by means of a needle valve 6, ll1is valve being movable vertinally in a bushinp 7 seeurqd on the plate 2. The plate 2 is l'ormod lo irovide a Cha1nber 8 with Which munecls a pipe 9, for cari' ing fl1e le tire angine or otl1or device in vvl1it*h it is to be 'usvd. lu tho plate and in a crosspieco 10 sorurod llwrolo are iorinod bearingxs for a slrail il, whiol1 oarries a valve 12 and on the upper end of slaafb 11, above plate 2, is a. handlo 13, so that by turning this handle tlie valve 19 is moved to cover more or less of the opening through pipe 9.

Socured to or lornmd integral. with the ed opening in the and of ar1n 15, this screw lioing preieralwly prmided 'Villl a lcnurled head. The screw 18 passes throngh an open ing in piece 16 and is provided with uuts or oollars, nue ou eilher side of the piece 16 s0 tlxat turuing (ho serow in its opening in arm 15 xvil] raise or lowor the end of the piece 16. The menus l'or securing the other end of the pie 16 (0 the eud of arm 11 is such as to permit l1e piece 16 to be moved films by srrew 18. The surfaces of the nuts or eollars wuirh coa -t Wil'li the opposite sides of piece 16 are prolorablv sphericallv lornxed so as to more readilv permit oi tl1o angular adjusbmont oi pieoe 16.

In using ilre carburetor, the liquid gasoleno is allowed to drop from the valve 6 down upon the bottom 1 of the spiral passageway boitween the eau 1 and tube 3, and H1e gasolono runs clown ihe inclined surface more or Air is drawn by the engine or othcr devise through the opening in can 1, and dmvnwardly through the spiral passagway botweon eau 1 and tube 3, and in passing ove1. (lie thin film of gasolene which overlies ll1o l)oi.tou1 of the spiral passageway, ihis air picks up gasolene vapor so as lo form a volatile gas. At the bottom of the spiral passagoney the gas passes into the oponin g in (ubp 3 and thon passes upwardly through tube 3 into chamber 8 and then through pipe 9 10 the engiue.. The amount of vapor entering tube 9 is controlled by the valve 12, the position of which may be ad(l0 justed by turning the handle 13. Adjust-- ment of this throttle-valve 12 by means f nandl 13, also adjusts the position of the i1edle valve 6 so as to vary the amount of inecl1anism may be so adjnsted as to permit n faster or slower feed of the gasolene. This adjustment is efiected by turning the screw 1850 as to increase or diminish the inclination 0f piece 16, and it Will oe seen that whenflthis inclination is changed, the emount 01. ve*tioal movexnent of valve 6 when valve 12 is closed and opened,,wfill be correspondingly change. 4

The carloureter above described is very simple in construction, may be manufactured et 10W cost and will withstand the hard usage to which it is necessarily subjecteck when used on an automobile. Furlhermore, with thisform of carbmter, a

' gas of very good quality is obtained, since the construction is such that bubbles or fine drops of liquid gasolene Will net be carried into the cylmder of the engine. This is due to the foot that the gasolene is spre ad out over a large surface on the bottom of the spiral passageway so that the air passing through the carburter moves over a large area on which there is 21 film of gasolene and then rises upward vertically before coming to the valve mechanism and the pipe leading to the engine.
